Full-Stack Developer Needed to Build Geospatial Web App (MapLibre, Vector Tiles, Payments)
I need a developer to build a geospatial mapping web application from scratch based on a detailed technical specification (I will provide). The app will serve as a professional site selection and analysis tool.

Interactive popups and right-side info panel with dynamic summaries (per LAD/LPA)
Layer toggles, filtering, and grouping logic
Data handling & performance:
Convert & serve large datasets (1–20GB+) efficiently as vector tiles (MBTiles/Cloud storage)
Optimise rendering for smooth performance at scale
Web platform features:
Build as a secure website (desktop + mobile responsive)
User login system (accounts & authentication)
Payment integration (Stripe or similar) for paid access tiers
Role-based access (free vs paid features)
Back-end & hosting:
Set up a scalable hosting solution (Cloudflare R2 / GCS / AWS)
APIs for user authentication and serving vector tiles
Modular, well-documented codebase for long-term maintainability
Deliverables:
Fully functional, production-ready web app with login and payments

Strong background in geospatial web development (MapLibre/Mapbox GL, Leaflet, Deck.gl, etc.)
Prior work with secure login systems and subscription/paywall models
Please share:
1. Examples of mapping applications you’ve built
2. Your experience with MBTiles/vector tiles and payment integration
